the oscilloscope i currently use is a Tek TDS3014. A big disadvantage of this scope is its very small memory with only 10k points.
The picoscopes are very intresting to me, especially the 6000 series. But since the Tek is a digital phosphor oscilloscope that tries to emulate the look of an analog scope, i dont want to miss this feature in my future scope. I know that your Software has a persistance mode and also an option that is called "analog intensity" but i do have some questions about it.
If you use the analog intensity setting, are different levels of intensity used for higher and lower frequency content of the actual signal or does the signal only decay after a certain time?
For example, when viewing a video signal (like here http://www.picotech.com/computer-oscilloscope.html
) it would be very nice to see a color shaded waveform. Could you supply an image?
The analog intensity mode should also be a mode to find random occuring events such as glitches. But this only makes sense when combined with a high update rate. The Agilent DSOX3000 series claims to have a maximum waveform update rate of about 1 million waveforms per second and there are videos where they measure a waveorm with a glitch every million cycles. These scopes seem to capture this approximatly once every second. Would this be possible with the picoscope in analog intensity mode?? If not, how fast ist the update rate in this mode? It would be nice to see the responsiveness of the display when viewing such a complex waveform in analog intensity mode!
